LAMP.

Speccation of Letters Patent No. 31,024, dated January 1, 1861.

ofair to the flame and thereby consuming the smoke, and my inventionconsists in forming a cap of one flat piece of metal which has certainprojectionsY and recesses of peculiar shape and arrangement, the saidpiece of metal being bent so as to form the body of the cap and so thattwo of its projections shall form a spring clip for grasping the wicktube of the lamp as fully explained hereafter, thereby producing aneffective and durable cap by a very inexpensive process.

In order to enable others to carry out my invention I will now proceedto describe the inode of manufacturing the same.

0n reference to the accompanying drawing which forms a part of thisspecification- Figure l is a side view of my improved cap connected tothe wick tube of a lamp, Fig. Fig. 3 an edge view of Fig. 1, and Fig. 4represents the shape of the plate prior to being bent to the formdesired.

' Similar letters of reference allude to similar parts throughout theseveral views.

I cut or punch from a thin sheet of brass or other suitable metal anydesired number of plates of the form illustrated in Fig. 4t. Each plateis in the first instance bent at the strip a which forms the connectionbetween the two halves A and A of the plate. The projections Z) Z) ofthe two halves are now directly opposite to each other. The next processis to secure these two projections together which is done by simplymaking a fold on each, lapping the fold of one projection into that ofthe other and hammering the two firmly together. Riveting or any othermode of fastening in which no solder is used may be substituted for thatabove described. The

two halves of the plate are now directly opposite to each other theprojections e e however pointing in contrary directions; theseprojections are now bent. so as to be adapted to the wick tube of thelamp, one projection being arranged to fit against one side and theother against the opposite side of the said tube as seen in the invertedplan view Fig. 2, and the two bent projections combined forming aspring-clip by means of which the cap is secured to and renderedadjustable on the tube.

of the plate Fig. t form the opposite sides of the upper end of the capwhile the (Fig. between these two sides.

The wick tube is inclosed by the cap as seen in dotted lines Fig. l, theair having free access to the interior of the cap from below andbecoming heated therein is di` rected toward t-he ignited wick the flameof which is consequently furnished with that plentiful supply of oxygenwhich insures a thorough consumption of smoke and deleterious gasesgenerated the consumption of coal oil and other burning fluid.

It will be seen withoutl further description that the above describedmode of manufacturing caps is -cheap simple and effective.

I lay no broad claim to an adjustable cap for directing a body of air tothe flame of a lamp nor do I claim broadly forming a spring clip on thelower end of an adjustable cap; but.

I claim as my invention and desire to secure by Letters Patent- As a newmanufacture, forming an adjustable cap for lamps of a single fiat pieceof metal having projections e and vand recesses of the shape andarrangement described, the said piece of metal being bent'as specified,so as to form the body of the cap and so that the two projections e eshall form a spring clip for grasping the tube of the lamp in the mannerset forth.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
